Kelly Clarkson says you have to be real special for her not to like you — and Dr. Luke is just that kind of special.

The pair collaborated on Since U Been Gone and Behind These Hazel Eyes when she was first getting started, during which time she developed a real distaste for the hitmaker — who she said never tried anything with her like with Kesha, but was very demeaning.

"There are many people in the world to befriend, and he is not one of them."

Ha! But for Kelly, this beef was serious — serious enough to lose "hundreds of thousands" or even "millions" in royalties when RCA forced her to reunite with Dr. Luke for My Life Would Suck Without You!

"Anytime I see someone pregnant, I just pray for them… [Pregnancy] was literally the worst moments of my life… I'm not kidding — I wish I were that girl that [had good memories of pregnancy]… But no. Nope. Don't miss it. It's as if someone was in an accident — they're pregnant, I'm like, 'Oh my God."'

Even though Miz Clarkson didn't enjoy the process of carrying a child, motherhood has its funny moments! For example, naughty daughter River once told her to "piss off" before bedtime. Kelly explained:

Love So Soft is by far one of the best songs she's ever released, and it's such a departure from what we usually hear from the 35-year-old. Even the accompanying video isn't what we would have expected from Kelly!
